ANKARA, Turkey (AP) — Turkey said that two more of its soldiers were killed Wednesday in a Syrian government attack in northwestern Syria, as steady clashes between the two national armies continued to rack up casualties.

Turkey has sent thousands of troops into the area to support Syrian insurgents holed up there, but hasn't been able to stop the Russian-backed Syrian government offensive to retake the Idlib province.

A Syrian opposition war monitor said nine Syrian soldiers were also killed in Turkish drone attacks in the northwestern area.

The Turkish Defense Ministry's statement said that the latest Syrian attack on its troops also wounded six soldiers. It did not provide further details.

The assault came as Turkish President Recep Tayyip Erdogan is scheduled to depart for Moscow where he says he aims to broker a cease-fire in Syria with Russian President Vladimir Putin.

Turkey and Russia are the two main power brokers in Syria and each of them support rival sides in the nine-year conflict.

“We expect to reach a shared view of the cause of the current crisis, its consequences and agree on a set of measures to overcome it,” Russian presidential spokesman Dmitry Peskov said about the upcoming meeting with the Turkish leader.

Russian officials have said they hold Turkey responsible for the collapse of a cease-fire agreement reached in Sochi, Russia in 2018. They say Ankara has failed to honor the deal and rein in militants who continued attacking Syrian and Russian targets.

In a statement, Konashenkov pointed out that under the 2018 agreement with Russia, Turkey was obliged to ensure that militants in Idlib pull 15-20 kilometers (10-12 miles) away from the de-escalation zone along with their heavy weapons. Instead of that, he argued, al-Qaida-linked militants “and other terrorist groups pushed moderate rebels north toward the border with Turkey.”

Konashenkov also assailed the West for turning a blind eye to Turkish military action in Syria "in violation of international law" and treating Turkish threats to destroy Syrian army units as a “legitimate self-defense.”

Syrian opposition activists reported intense clashes near the government-held town of Saraqeb that sits on a major highway that links Syria's two largest cities, Damascus and Aleppo. The Britain-based Syrian Observatory for Human Rights, an opposition war monitor, said Turkish drone attacks near Saraqeb killed nine Syrian soldiers.

The Russian military said in a statement Wednesday that “a group of terrorists” made a failed attempt to detonate ammunition placed next to chemical storage tanks in the western part of Saraqeb two days ago. It claimed that the failed attempt was a bid to blame the Syrian government for launching a chemical attack.

The Russian military said the militants got poisoned when one of the tanks leaked before they could detonate the explosives.

Clashes between Turkish and Syrian forces in northwestern Syria have killed 58 Turkish troops in the past month, including 33 soldiers killed Thursday in a single airstrike.
